The chambers 10 and 1-1 are embodied in the lowersection "6, and the chamber 12 Yisjlocated inthe upper section 7.Thewater v chamberIlO is materially larger than the remainiugchamhers l1and l2lan'd the chamber is-reduced in vertical extent so as to confinethevdry'steam therein and conserve thepressure of said steam. The uppersec-' tion 7:11:15 atop plate or covering 13 formed at regular intervalswith. a r plurality of openorganization embodyingthe features of theings 14E surrounded by internally vscrevvthreadedcollars .15, theopenings-1 L and collane 15; being sdisposed at regular intervals and;.in ,syinmetrical positions over the top 4 plate 13. 1 The bottom 16 ofthe chamber 12 also has a plurality of openings 17 formedthereinsurrounded by collars 20, and below the latter openings and collars thebottom plate 16 of the chamber 12 has two openings 21 therein and alsosurrounded by collars 22 projecting upwardly into the chamber a suitabledistance above the bottom f plate 16. Connected to the front end 23 ofthe chamber by means of suitable collars 24 and connecting devices 25and opening into the said'chamber are vertically disposed wet steamconveying pipes 26 having rearwardly extending conveying pipes 27 ofsmaller diameter and connected to the upper ends'the-reof by suitableconnecting devices 28 and continuing in the form of furtherdiametrically reduced pipes 29 and 30, respectively extending forwardand rearward in looped form and united by connecting devices 31 and 32.The rearends of the rearwardly extending reduced pipes 30 are united byconnecting devices 33 to vertically disposed branch pipes 34fextendingthrough the openings 19 within the collars 20 and secured in theopenings 21 within the collars 22 and fully opening into the upperportion of the dry steam chamber 11. The vertical branch pipes 34 areimperforate and as shown by Fig. 3 pass through the oil chamber 12. I

As shown by Fig. 2, an oil supply pipe ,35 is "connected with and opensinto the chamber 12. To the lower portions of the unions 25 a watersupply pipe 36 is connected and the oil supply pipe 35 and water supplypipe 36 are also connected to the bottoms of oil and water supplyreservoirs 37 and 38, the pipes 35 and 36 having valves 39 and 40, forregulating or cutting ofit the flow of the oil and water from thereservoirs 37 and 38 as may be found necessary. The oil and waterreservoirs 37 and 38 are adapted to be located any suitable distancefrom the improved burner organization and each has a central rod 39disposed therein for operation therewith of a float 40, the float beingfixed to the rod and the latter vertically movable in suitable guidedevices as, for instance, a bracket arm 41 as shown in the reservoir 38,and lower guides 42 at the bottom of each of the reservoirs, it beingunderstood that the bracket arm 41 may be duplicated in the reservoir37. On each rod are a pair of collars 43 between which the inner end ofa lever 44 is mounted and intermediately fulcrumed on an. ear or lug 45projecting from a supply valve casing 46 having a discharge outlet 47and a springactuated valve stem 48 risingfrom the top thereof and formedwith a rounded head 49 on Whic'hthe free end of the lever 44 hasbearing. The valve within the casing 46 may be of any suitable type,such, for instance, as a vertically movable plug valve, and connected toone side of the supply valve 46 is a supply pipe 50, which projectsoutwardly through the side of the reservoir. This construction is alsoduplicated in the reservoir 38, the rod 39 in the latter reservoir beingshorter than t-he said rod in the reservoir 37 in view of the differenthorizontal locations of the two chambers 10 and 12 with which therespective reservoirs 38 and 37 are connected. The supply pipesextending outwardly from the supply valves 46 will be respectivelyconnected to a suitable oil and water supply and it will be seen thatthe level of the water and oil in the reservoirs 38 and 37 is the sameas the level of the water and oil in the chambers 10 and 11, asindicated by dotted lines'in "Figs. 2 and 3 and also partially infulllines in the latter figures. It is intended. that the predeterminedlevel of the water and oil in the chambers 10 and 12 be uniformlymaintained through the automatic operation of the float and supply valvemechanism in the reservoirs 38 and 37. The reservoirs 37 and 38 are alsopreferably closely arranged as shown by Fig. 2 and may be one structuredivided by a central partition. However, the exact manner of formingthese reservoirs and positioning the same may 'be varied at will, andalso the automatically operating means therein for ma'intaininga uniformlevel ofthe water and oil in the chambers 10 and 12. As shown, thereservoirs 37 and 38 have a common top cover orplate 51, and it will ,befurther understood that the pipes 35 and 36 connected to the bottomportions of these reservoirs will be of any length desired and have ageneral contour that may benecessary in making connection with thechambers 10 and 12.

Below the bottom of the water chamber 10 an oil conveying pipe 52 isdisposed and transversely looped or. bent as illustrated by Flg. 1, toincrease'the circulation of the oil or cause the latter to have as longa conveyance as possible beneath the water chamber and at the rear endof the burner organization this pipe 52 is continued in the form of avertical branch 53 a suitable distance above the top of the plane of theoil chamber 12 and then regularly projected for wardly andrearwardly inthe "form of vaporizing loops 54, the uppermost loop being continuedforwardly a greater distance than the loop below and connected to avertical pipe 55, which opens through the top 56 of a regulator 57 Thisregulator and the looped pipes 54 may or may not be used, as desired, inview of the factthat the conthat are omitted in more simplified instal-ilatlons. It may also be found necessary in some-installations todispense with the oper-- ation of the vaporizing coil 54, its connection53 and the conveying .pipe 52, and if such be the case, the supply ofoil may be' shut off from the conveying pipe through thegmediumrof avalve59' located adjacent to the union 58. 1 The regulator 57v may alsobe of any preferred type, but one practical form thereof is shown byFig. 3 and consists of :an outer casing or shell 60 having a lowerrounded bottom'6 l and therein is fitted a valve case 62 of lessdiameterthan the shell,

said valve case. having a screw-threaded:connection; asat 63, with theupper portion or the case or shell 60 and provided with a horizontalflange 64, which rests on the upper edge of the casing or shell 60 andto which'the topplate or cover 56iis secured. Withinthe valve casing 62a hollow valve 65 is rotatably mounted and is secured to a stem 66having bearing in" the lower end of the" casing 62 and "extendingupwardly through a suitable bearing or collar 67 in the top portion ofthe valve 65 and also through an'opening68 in the top or cover plate 56."The top or cover plate56 is projected any suitable distance towards the7 front in the form of an indicating segment 69 having opposite stopflanges-70 at the ends'thereofand onits upper surface inscribed withcharacterswhich in the present instance consist of a cipher (0) and the'nu' m'erals l, 2, 3 and 4. Cooperating with this indicating segment andthe characters thereon is a horizontally disposed valve lever71 attachedat its inner extremity to the upper end of the valve stem 66. The casingor shell 60 at its rear-portionhas a union 72 projecting rearwardlytherefrom for connec-- tion of a pipe 73, which has its rear endinengagement with a collar or union 74 in the central portion of the frontend of the chamber 12. The opening through the rear portion of the unionis reduced; as at 75, and

is wholly above the maximum level of the,

oil in the chamber 12, as shown by the dotted lines. 'Through the'adjacent walls of theinner valve casing '62 and valve 65 are ports 76and 77, the port 76, always'standthe port 70. When the'valve 65 isturned to certain positions,i,the ports 77 1 and 7 6 will be varied asto the opening, space pro-i vided by the same relatively to the openingor .port 75. An annularspaceror chamber 78 is formed between the valvecasing 62 mg in alinement with the inner terminal of' and the outervalve casing or shell 60, and this annular space is continuous with alower chamber 79 between the bottom of the inner valve casing 62 and theouter casing or shell 60. Connected to the lower portion .of the chamber79 is a dry steam pipe 80,

which as shown by Fig. l'projects laterally andjis'continued by anangular branch 81, which in turn is secured to a cross return branch82,connected to the unions 32 of the reduced dry steam forming pipes 29and regulate'the quantity of the dry steam passing'through the bottom ofthe regulator 57 or into the chamber 79, or the supply of steam may beentirely out oifwhen the regulator is not in use. The valve 65, ashereinbefore indicated, may be adjusted to regulat'ethe size of theopenings between the registering'ports 76 and 77 to entirely close offany registration, of these ports,-and the indicating characters on thesegment 69 will give correct information as to the adjustment. When thelever 71-is turned fully over the cipher (0), the valy e 65 will beclosed, or the port 77 thereof will not register with the port 76. Whenthe lever 77 is turned to register with the numerals 1, 12 and 3, theports 76 and 77 will be opened, respectively, one-fourth, one-half andthreefourths, and when the said lever is turned fully'over to registerwith the numeral 4, the ports 7 6and 77 will have full registration, orbe-completely open.

At regular intervals over the upper portion of the body or main element5 a plurality of burner units 84 are disposed and each unit consists ofan outer shell 85 having an upper round or semicircular top '86 withperforations 87 formed therein The lower extremity of the shell 85 hasan integral stop collar 88 and exterior screw threads 89, which, areadapted to separably engage the threaded collar 15 around the opening 14and rising from the top plate or covering 13 of the oil chamber 12. Thelower end 'of the shell 85 terminates coin'cidently with, the lowersideof the top cover or plate 13, as clearly shown by Fig; 3, and the saidshell is of equal diameter throughout its extent.- Within the shell 85is a shell 90, of less diameter but of essentially the same contour,toproduce an annular chamber 91 between the two-shells, the upper roundedor semicircular end eaof the inner shell being. formed with perforationsor openings '93. The lower portion of the inner shell .is diametricallyreduced and provides a chamber 12 and the dry steam chamber 11,

as the neck 94: of the inner shell 90' is imperforate. The annularchamber 91 between the two shells and 90, however, is fully open at itslower. terminal through the oil chamber 12, and by this means the oilvapor is permitted to unrestrictedly pass upwardly between the twoshells and the dry steam from the chamber 11 is free to pass upwardlyinto the inner shell, the dry steam and oil vapor mingling within thespace between the upper semicircular ends or heads 86 and 92- ofthe-respective shells in proper proportions to form an advantageouscombustible heating medium. The upper extremities of the burner units 81 stand above the adjacent pipes and these units as a whole will providefor an intense heating action within a furnace chamber for both domesticand general commercial usage. The shells 85 and 92 are readilyremovablefrom their respective collars 15 and 18 for cleaning purposesand to give access to the'chambers 12 and 11, and it will be understoodthat when necessary the said burner units may be replaced by similar newdevices without affecting the remaining burner units that may still bein practical working order. The pipes 27, 29, 30 and the vaporizing loop54: are located between portions of the burner units, and the heat fromthe latter affect the said pipes and vaporizing coil 'to effectively drythe steam and vaporize the oil when the vaporizing coil 54: is open foruse.

Below the conveying oil pipe 52 supplemental burners 96 are horizontallydisposed and consist of burner tubes 97 having a plurality of upperopenings 98. The burner tubes 97 are closed at their rear ends bysuitable caps 99 and connected at their front ends to a T-shaped supplyor cross branch 100 having a supply pipe 101 adapted to be connected toa gas main and provided with a valve 102, by means of which the gas fromthe main may be cut off as hereinafter more fully explained. TheT-shaped or cross supply branch 100 also has a cross vapor pipe 103 withtwo outlet branches 104: opening into the said T-shaped supply or crossbranch adjacent to the outer ends of the burner tubes 97. The vapor pipe103 is connected by a supply pipe 105 with the top portion of the unionor connection 72 for the pipe 7 3, which establishes an open way betweenthe front portion of the chamber 12 and the regulator 57, this regulatorserving, as hereinbefore indicated, to admit an auxiliary vapor supplyto the several burner units, or, specifically, to the lower portions ofthe annular chambers 91, to supplement the vapor produced in the chamber12. The pipe 105 will operate as a supply means relatively to the vaporconnection for the tubular burners 97 even though the valve 67 may beclosed and the conveying pipe 52 cut off through the medium of the valve59,

in view of the fact that the pipe 73 is open to the chamber 12 and vaporfrom this chamber may pass into the pipe 105. In starting the improvedburner organization it is proposed to use ordinary from a street serviceadmitted through the pipe 101 and to the burner tubes 97. By this meansthe burner organization will be thoroughly heated and steam formed aswell as oil vaporized in the respective chambers 10 and 12 and passthrough the courses hereinbefore explained and into the burner units insuch proportions as to produce a combustible heating medium, and ifdesired the .burner tubes 97 may continue to act as heating means withfuel supplied from a gas main, but it is preferred that afterthe burnerorganization as a whole has been caused to operate for some time toautomatically produce hydrocarbon vapors and dry steam, the valve 101 beclosed and the hydrocarbon vapor be fed to the said burner tubes bymeans of the pipe 105 and cross vapor pipe 103. By this means it will beseen that the burner organization will supply a heating medium for theburner tubes 97 independently of any gas main, with economy in theheating operation;

As hereinbefore indicated, the simplified operation of the burnerorganization will be through the medium of the burner units 84independent of the vaporizing coil 54, the oil conveying pipe 52 beingthen cut off by closing the valve 59 and thereby also eliminating theregulator 57 controlling the auxiliary or supplemental supply ofhydrocarbon vapor and dry steam. This simplified operation will besufficient for ordinary domestic use, or in small domestic heatingfurnaces. In larger installations such as steam boilers, locomotive andmarine engines it will be preferred to use the vaporizing coil 54 withthe conveying pipe 52 in connection therewith and also the regulator 57controlling the auxiliary supply or supplemental mixture, ashereinbefore explained, and regulable through the adjustment of thelever 71 and valve 65. In some instances the simplified form of theburner organization will be used without the vaporizing coil 54 andconnections therefor and the regulator 57, it only being necessary toclose the openings where the several parts of this auxiliary attachmentare connected by means of caps or screw plugs without in the leastmodifying the simple operation of the burner its w ich. will hen e euplied wi hllytl ig e 'bfill:W9 39111 d elle I2; end'dry steamfronithe uh 1 p;
